How to open an HTML file in QtextBrowser-CodePudding

I have a ready-made HTML file, if it is opened through a browser, then a normal web page is displayed.

How can this HTML file be opened via the QTextBrowser widget so that structured information is also displayed in it as a web page?

I've tried something like this:

QFile file("/home/alex/data.html");
if(!file.open(QIODevice::ReadOnly))
    QMessageBox::information(nullptr,"info",file.errorString());
QTextStream in(&file);
ui->textBrowser->setHtml(in.readAll());

but it didn't work out.

There are dedicated classes to display full webpages:

In your case, QTextBrowser can "only" display rich text following HTML tags.
